Computers to be "oxygen of the future"

According to this article, each person will not only carry 2 or 3 devices with them but rather hundreds of digital devices with them in the future, which some will be woven into our clothes and used as identification markers. These devices may even tell our washing machines what cycles to use. Predictions such as these came from Cambridge-MIT Institute's Pervasive Computing initiative (CMI). They claimed that these digital devices will act as communicators who will talk to each other and to humans wherever we may be. Based on the device that they created, unauthorized use and attack was nearly impossible. The negative side is that there was no way of escaping from the system. It would find whatever communications that was available and call. MIT's Umar Satif stated, "The computer was just trying to be helpful, but it turned into the nightmare scenario because there was no way of shutting the system down".


What ways can devices such as these benefit us? Are we really ready to let computers take over of lives this much? How would the world be if everything was control by computers?
